Question

1. VACUUM CLEAR 1901

Here's how inventor H. Cecil Booth came up with the idea. He noticed a device on trains that blew dust off chairs and thought it would be better to have a device that sucked the dust instead. To test his idea he laid a handkerchief on a chair, put his mouth on it and sucked as much dust as he could. Seeing the amount of dust and dirt on the underside of the hanky effectively made it the first vacuum cleaner filter and realized the idea could work. It's a good thing he wasn't looking to invent a machine that cleans manure.

2. DISPOSABLE RAZOR BLADES 1909

Invented by King Camp Gillette (the best a man can get) as an inexpensive alternative to using a straight razor. The straight razor was like going to your kitchen and taking a chef's knife to your face. Instead of paying two bits for a shave and a haircut, men could save one bit and just get the haircut, likely parted down the middle.

3- Controlled Airplane 1903

Orville and Wilbur Wright didn't invent the first airplane, but applied the principles of jumping before flying. Through a lot of trial and error, building their own wind tunnel, and testing 200 wing designs they were finally able to fly their prototype 121 ft (37m) in 12 seconds. The design was further improved with regards to safety, power, and control to the point in October of 1905 when the aircraft could maintain a sustainable flight and land with pilot safe and the craft undamaged. Today we see the airplane's influence in aeronautical engineering, transportation, and warfare. It was only a matter of time before the Mile High Club was invented.

4- PARACHUTE 1913

With the invention of the plane it is only natural to invent the parachute. Although the idea of the parachute has been around since the 15th century, Slovakian inventor Stefan Banic is credited with the invention of the first one widely used by the military. He donated the U.S. patent to the U.S. Army and received little fame or fortune for it. The parachute was used extensively during World War I. Today it continues to be used in military and civilian aircraft as well as by thrill seeking skydivers.

5- LIQUID FUEL ROCKET 1914

Powered by liquid oxygen and gasoline, the first flight of a liquid fuel rocket occurred on March 16, 1926. American professor Robert H. Goddard launched it and it rose 41 feet and flew for 2.5 seconds. It demonstrated that liquid fuel rockets were possible, eventually leading to Sputnik, the Moon Landing, and the movie Armageddon- effectively making Ben Affleck a superstar.

Answer 1

Resposta:

VACUUM CLEAR 1901

Eis como o inventor H. Cecil Booth teve a ideia. Ele notou um dispositivo em trens que soprou a poeira das cadeiras e pensou que seria melhor ter um dispositivo que sugasse a poeira. Para testar sua idéia, ele colocou um lenço em uma cadeira, colocou a boca nela e aspirou o máximo de poeira que pôde. Ver a quantidade de poeira e sujeira na parte de baixo do lençol tornou efetivamente o primeiro filtro de aspirador de pó e percebeu que a idéia poderia funcionar. Ainda bem que ele não estava pensando em inventar uma máquina que limpe o esterco.

2. LÂMINAS DE ARROZ DESCARTÁVEIS 1909

Inventado pelo rei Camp Gillette (o melhor que um homem pode obter) como uma alternativa barata ao uso de uma navalha. A navalha era como ir à sua cozinha e levar uma faca de chef ao seu rosto. Em vez de pagar dois bits por um barbear e um corte de cabelo, os homens poderiam economizar um pouco e apenas cortar o cabelo, provavelmente dividido no meio.

3- Avião Controlado 1903

Orville e Wilbur Wright não inventaram o primeiro avião, mas aplicaram os princípios de pular antes de voar. Através de muitas tentativas e erros, construindo seu próprio túnel de vento e testando 200 projetos de asas, eles finalmente conseguiram pilotar seu protótipo de 121 pés (37m) em 12 segundos. O projeto foi aprimorado ainda mais com relação à segurança, potência e controle, até o ponto em outubro de 1905, quando a aeronave poderia manter um vôo e aterrissagem sustentáveis com o piloto seguro e a aeronave sem danos. Hoje vemos a influência do avião na engenharia aeronáutica, transporte e guerra. Foi apenas uma questão de tempo até que o Mile High Club fosse inventado.
